Abstract
New optical absorption bands can be engineered by combining two different phases into a superlattice using atomic layer-by-layer molecular beam epitaxy as shown in the figure. Transitions from one layer to another occur at frequencies determined by the electronic structure of the component layers and how the energy levels of the two materials line up at the intrfaces.
